Young's modulus of elasticity: Weight stretches wire.
1R20.15 • C+90+10
Young's modulus of elasticity: Weight stretches wire. Weights are added to a vertical wire. The wire is attached to a mirror assembly. As the wire stretches, the angle of the mirror changes. A laser beam is bounced off the mirror, and the stretching of the wire is shown by the movement of the laser beam on the screen. MECHANICAL PROPERTIES OF MATERIALS
